Someone said that mcu design is more difficult.An engineer is capable of doing mcu design will of course be capable of doing SOC design in video area.Is that true?
For instance,a 16 bit multiplier is designed.It is impossible to test all possible inputs and its outputs.Then,when we do verification how can we say this mulitiplier's function is right?
Is "set_clock_skew" still used in DC?
I found the following comment in a EDA forum"
"set_clock_skew is a outdated command now,
set_clock_skew -uncertainty has been replaced by set_clock_uncertainty
set_clock_skew -propagated has been replaced by set_propagated_clock.
Is that comment true?I...
wether the length or the width of the MOSFET is 0.18um?

I synthesized one of my designs,and i am trying to calculate the gate count.
The DC reported the total area of my design.
I also synthesized a NAND gate ,the reported area is 7.53.And a NOT...
The coefficients of this signal is controlled by a variable parameter,the coefficients are calculated according to the parameter everytime and then the output is produced using the updated coefficients.
The question is how to simulate this kind of filter,for i can not define a transfer function...
I read one paper today,and Ladner-Fischer adder(LFA) is said to be the fast adder in this paper.But it seems that carry lookahead adder(CLA) is more frequently used for high speed application.And in this paper the data presents that LFA is faster than CLA,and also cost smaller gates than CLA.
If...
